Inheritance diagram for wxSizerItem:

Detailed Description

The wxSizerItem class is used to track the position, size and other attributes of each item managed by a wxSizer.

It is not usually necessary to use this class because the sizer elements can also be identified by their positions or window or sizer pointers but sometimes it may be more convenient to use it directly.

Library: wxCore

void wxSizerItem::AssignSpacer ( const wxSize & size )

Set the size of the spacer tracked by this item.

Old spacer, if any, is deleted.

In other words, for sizer items, all of the child elements must be hidden for the sizer itself to be considered hidden.

As an exception, if the wxRESERVE_SPACE_EVEN_IF_HIDDEN flag was used for this sizer item, then IsShown() always returns true for it (see wxSizerFlags::ReserveSpaceEvenIfHidden()).

Sets the numeric id of the wxSizerItem to id.

void wxSizerItem::SetInitSize	(	int	x,

Set the proportion item attribute.

void wxSizerItem::SetRatio	(	int	width,
		int	height
	)

Set the ratio item attribute.

Set the ratio item attribute.

void wxSizerItem::SetRatio ( float ratio )

Set the ratio item attribute.

void wxSizerItem::SetSizer ( wxSizer * sizer )

Set the sizer tracked by this item.

Deprecated:: This function does not free the old sizer which may result in memory leaks, use AssignSizer() which does free it instead.

void wxSizerItem::SetSpacer ( const wxSize & size )

Set the size of the spacer tracked by this item.

Deprecated:: This function does not free the old spacer which may result in memory leaks, use AssignSpacer() which does free it instead.

void wxSizerItem::SetUserData ( wxObject * userData )

void wxSizerItem::SetWindow ( wxWindow * window )

Set the window to be tracked by this item.

Deprecated:

Todo:: provide deprecation description

void wxSizerItem::Show ( bool show )
